COFFEE-POT.

Specification of Letters Patent.

Patented March 17, 1908.

Application filed June 10, 1907. Serial No. 378,168.

To all whom it may concern:

Be it known that I, I'IORACE L. TVELLs, a citizen of the United States,residing at New Haven, in the county of New Haven and State ofConnecticut, have invented a new and useful Improvement in Cofi'eePots;and I do hereby declare the following, when taken in connection with theaccompanying drawings and the letters of reference marked thereon, to bea full, clear, and exact description of the same, and which saiddrawings constitute part of this specification, and represent, in

Figure 1 a view in side elevation of a coffee pot constructed inaccordance with my invention, a portion of the body of the pot beingbroken away to show the coffee-container in its lowered position. Fig. 2a plan view of the coffee pot. Fig. 3 a broken view thereof in verticalsection,s howing the coffee container in its elevated position. Fig. 4 adetached view in side elevation of the cap of the coffee-container Fig.5 a plan view thereof. Fig. 6 a reverse plan view thereof. Fig. 7 adetached view in side elevation of the coffee-container body. Fig. 8 areverse plan view thereof. Fig. 9 a detached plan view of the lockin-plate. Fig. 10 a similar view of the slotted caring collar.

My invention relates to an improvement in coffee pots, the object beingto produce a coffee pot operating on scientific principles andconstructed with particular reference to simplicity and durability ofconstruction, ease of comprehension, convenience of use, and toadaptation to the making of coffee in several different ways withoutextracting the tannic acid from the coffee.

With these ends in view my invention consists in a coffee pot havingcertain details of construction as will be hereinafter described andpointed out in the claims.

In carrying out my invention as herein shown, I employ a cylindricalbody 2 having a spout 3 and handle 4 of any approved construction andfurnished with a cover 5 provided with a centrally arranged collar 6formin a suspension bearing for a vertically movabl e and rotary spindle7 furnished at its upper end with a knob-like handle 8 and carrying atits lower end the disk-like cap 9 of a cylindrical coffee-container alsocomprising a shallow cylindrical container-body 10, relatively large ascompared with the cylindrical body 2 of the pot so as to secure the fullvalue of centrifugal force as an aid to extracting the coffee principlefrom the ground coffee, the larger the coffee-container in diameter thegreater being the action of centrifugal force.

Annular grooves 11 and 12 located near the lower and upper endsrespectively of the spindle 7 receive the fork-like inner end of alocking-plate 13 radially arranged upon the top of the cover 5 which isfurnished with a slot 14 for the reception of a screw 15 passing upwardthrough the slot 14 and through the plate 13 into a knob-likefinger-piece 16 by means of which the plate is moved inward and outwardinto its locking and releasing position. For the entrance of thefork-like inner end of the plate 13 into the grooves 11 and 12, thesides of the collar 6 are formed with slots 17 as shown in Fig. 10.Under this construction the spindle is suspended in the said collar 6 inan elevated or in a depressed position with freedom to be rotated ineither position.

The ca 9 of the coffee-container is provided witii a star-like reinforce18 the points of which extend to the edges of the cap and are applied toradial arms 19 produced by cutting the central portion of the cap awayto form quadrant-shaped openings 20 for the exposure of a fine wirescreen 21 located within the cap and ring-shaped for the reception atits center of a circular wire screen 22 of coarser mesh. This particularconstruction, however, may be changed according to requirements.

The container-body 10 is cut away to form a circumferential lateralopening 23 occupied by wire cloth 24. The bottom of the container isformed with a central opening 25 closed by a disk of wire cloth 26. Bypreference and as shown, the body 10 of the container will be reinforcedby a wire frame 27 over which its metal portions are bent. The saidcoffee-container is provided near its upper edge with pins orprojections 28 entered into bayonet-slots 29 in the downwardly turnededge of the cap 9. It will be noted that the coffee-container issupported entirely from abovefrom the cover of the body 2, there beingcomplete clearance or a free space between the bottom of the containerand the bottom of the body of the pot. There is therefore nothing toprevent the water in the pot from being sucked directly upward into thecoffee-container into the center thereof By constructing thecoffee-container as described, it will, when rotated, by twirling thespindle 7, draw in water at its top and bottom and discharge it bycentrifugal force through its sides. In this way the water may be drawnquickly through the ground coffee again and again for the extractiontherefrom of as much of the coffee principle as desired. On the otherhand, the coffee may, if preferred, be made without any rotation of thecontainer, though, as ex lained, that hastens the making of the co ee.\Vhen the infusion has reached the required degree of strength, thespindle 7 is lifted as high as it will go and the lockingplate 13 pushedinward to enter the roove 11 in the lower end of the spindle W ereby thecoflee-container will be suspended in the elevated position shown inFig. 3, and there it may be twirled for the extraction of the last dropof the coffee infusion and then left until the time comes for washingthe pot. In most, at least, of the modern coffee pots designed toextract only the desirable principles from the coffee, the ground coffeeis located at the top of the pot entirely above the water which must bebrought to a sharp boil before it will be forced upward through thecoffee. In my im roved coffee pot, on the other hand, the co ee isimmersed in the water during the entire period covered by making theinfusion and then lifted out of the water at the moment the infusion hasreached the required strength. The infusion may therefore be made at anydesired tem. perature. Thus, the water may be cold when the coffee isimmersed in it, and gradually brought to a boil, or the water may begradually brought near to the boiling point and never allowed to boilbefore the coffeecontainer is lifted out of it, or the water may be brouht to any desired temperature, or even to t 1e boiling point before thecoffee is immersed in it, &c. It will thus be seen that my improvedcoffee-pot offers a wide rangeof choice in methods of making coffee; atthe same time it provides for conveniently and easily removing thecoffee from the infusion just as soon as the same has reached thestrength desired.

It is apparent that in carrying out my invention, some changes from theconstruction herein shown and described may be made. I would thereforehave it understood that I do not limit myself thereto but hold myself atliberty to make such departures therefrom as fairly fall within thespirit and scope of my invention.

1. In a coffee pot, the combination with the body and cover thereof, ofa rotatable and vertically movable spindle formed at its upper and lowerends respectively with annular grooves for its suspension in the saidcover, a coffee-container carried by the lower end of the spindle, andlocking means carried ported entirely from the said cover.

2. In a coffee pot, the combination with the body and cover thereof, ofa slotted collar mounted in and extending above the top of the cover, avertically movable and rotatable spindle bearing in the said collarformed at its upper and lower ends respectively with annular grooves forits suspension in the same, a coffee-container carried by the lower endof the spindle, and a locking-plate entering the slot in the collar forengagement with L the grooves in the spindle for suspending the 5 samein its elevated and depressed positions respectively, in the said cover,with freedom to be rotated in either position there being a spacebetween the bottom of the container and the bottom of the body when theformer is in its depressed position in which it is supported entirelyfrom the said cover.

3. In a coffee pot, the combination with the body and cover thereof, ofa vertically movable and rotatable spindle having bearing in the centerof the said cover, means for suspending the spindle in its elevated anddepressed positions respectively, in the said cover, with freedom to berotated therein, and a coffee-container consisting of a cap fixed to thelower end of the spindle, and a removable container-body attached to thesaid cap, the cap and container being formed with openings filled withwire cloth and there being a space between the bottom of the containerand the bottom of the body when the former is in its depressed positionin which it is supported entirely from the said cover. Y

4. In a coffee pot, the combination with the body and cover thereof, ofa vertically movable and rotatable spindle having bearing in the centerof the said cover, means for suspending the spindle in its elevated anddepressed positions respectively, in the said cover, with freedom to berotated therein, and a coffee-container consisting of a cap fixed to thelower end of the said spindle, and a container-body removably applied tothe said cap, the body being reinforced by a wire frame, and the saidcap and body having openings filled with wire cloth.
